Each entry is 0x16 bytes long.

These notes will go off observations and patterns found in the file alone, not tests in-game.

0x00 - Abilities with a value here prevent certain stat drops. (Clear Body, White Smoke)
0x01 - Unknown
0x02 - Unknown
0x03 - Unknown
0x04 - Not sure. Is usually 01.
0x05 - Used by absorbing abilities. (Water/Volt Absorb) 0x04 will be the move's Type that will be absorbed. In hindsight, this byte handles what type the Pokemon is immune depending on the ability. This is a better explanation considering Flash Fire and Levitate both use this, but don't restore HP.
0x06 - 0x07 - Abilities with a Status ID value here make the user immune to a certain status condition.
0x08 - 0x09 - Same as 0x06 - 0x07
0x0A - 0x0B - Same as 0x06 - 0x07
0x0C - 0x0D - Same as 0x06 - 0x07
0x0E - 0x0F - Possibly the same as 0x06 - 0x07
